The COVID-19 pandemic has affected college students, leading to increased anxiety and emotional distress. This study investigated how perceived public health crises relate to anxiety levels in college students, and how social support and gender influence this relationship. Data from 3,165 college students from six universities in Shaanxi Province, China, were collected and analyzed by using AMOS and SPSS PROCESS 4.0. Results showed that perceived COVID-19 risk significantly impacted anxiety levels, and social support moderated this relationship. Gender also had multiple interaction effects with social support and perceived pandemic risk on anxiety. Overall, the study confirms that COVID-19 quarantine and perceived risk increase stress and anxiety in college students, with social support playing a buffering role, albeit with variations based on gender.新型冠状病毒肺炎（COVID-19）疫情对大学生群体造成了显著冲击，导致其焦虑水平与情绪困扰程度显著上升。本研究探究了大学生感知到的公共卫生危机与其焦虑水平之间的关联，以及社会支持与性别对该关联的调节作用。本研究收集了中国陕西省6所高校共计3165名大学生的调研数据，并采用AMOS与SPSS PROCESS 4.0软件进行分析。研究结果显示，大学生感知到的新冠疫情风险对其焦虑水平存在显著影响，且社会支持对该关联起到调节作用。性别还与社会支持、感知到的疫情风险在焦虑水平上存在多重交互效应。综上，本研究证实新冠疫情防控隔离措施与感知到的疫情风险会加剧大学生的压力与焦虑情绪，而社会支持可发挥缓冲作用，不过该作用会因性别不同而存在差异。
